The demise of BGP from unrestrained table growth has been predicted for decades. Part of this is because my million dollar router has a slower central proc and less RAM than my $2k laptop. So yeah, pigs can fly with sufficient thrust, but we are currently using hamsters on a wheel level thrust. There is a middle ground.

Before we claim BGP is dead again, let's take a moment and ensure we didn't cripple it first. The protocol, as Chris said, has no inherent problems scaling for the a while at least. It may not be "optimal", but there is something to be said for a protocol with a 100% installed base that works, and works well.
